It's hard to figure out which are the good points and which are hyperbole. "EDSAC was the second electronic digital stored-program computer to go into regular service" and with "the world's first assembler" dating from 1949, says the Wikipedia reference. As such, many languages can be traced back to that "Most Godawful Computer on Earth (TM)".

Or, "4. ALGOL60 [4] had many nice features of languages today but was too theoretical: only existed on paper." Yet its reference 4, at https://en.wikipedia.org/wiki/ALGOL_60#ALGOL_60_implementati... , lists a number of ALGOL60 implementations even in the 1960s.

Hyperbole and reference will probably be worked on in next one. ALGOL mostly existed on paper or in complex compilers on expensive systems. The "computer" that is the EDSAC is not on that list. So, they would have to build their own ALGOL... a difficult thing anyway in that period... using a machine and process like this:

Can you imagine trying to make a robust, fast compiler for such a weak machine in tape batches on that weak machine? I could understand them giving up with BCPL as a useful result on that machine. The cost-benefit analysis of using a PDP-11 like an EDSAC is opposite. Wirth et al showed you could do better. C inventors just liked BCPL. I'd understand if they used BCPL to bootstrap a Modula-2 or other ALGOL subset with good design. Instead, they kept trying to force BCPL to do something it wasn't designed for... wait, it wasn't designed period lol. It was just what compiled on a 1940's calculating device.

It's bad foundations vs others' good foundations. Might have worked for them sure. Today, though, we need to know why they did it that way and why we definitely shouldn't if we don't absolutely have to. That's the point of the essay. Plus, to clear up associated misinformation.

Algol60 could never be taken seriously as a mainstream language, lacking Algol-like syntax.
Algol60 lacked Algol-like syntax?

In one sense, that's almost tautologically impossible. I presume you mean "like the other Algols", which makes it a non-absurd statement, but... could you expand or clarify what you mean here?

I believe it's a joke. Gold isn't a gold-like substance because it is gold. Algol isn't an Algol-like language because it's Algol.

If so, I don't believe it's a good joke.

It's a joke, but not the one you thought.

The joke is that the syntax of Algol didn't actually look all that much like what people mean when they say "Algol-like syntax". No curly braces anywhere to be seen.

As my introduction to Algol-like languages was through Pascal, the joke completely passed me by.
I could see that putting you in a place where encountering people misusing "Algol-like" to mean C-like, when trying to distinguish from something more like Algol, would be extra noticeable and annoying.

Likely you have just been lucky :)
